Title of Talk: Out-of-equilibrium contributions to charm hadrons in a fluid-dynamic approach
Abstract: Building on previous studies that demonstrated the applicability of a fluid-dynamic description of charm quarks in the quark-gluon plasma, in the present talk I will present an approach to computing the out-of-equilibrium contributions to the distribution function of charm hadrons. This work focuses on including corrections arising from the initial out-of-equilibrium distribution of charm quarks after a free-streaming phase, as well as from the freeze-out surface within fluid dynamics. These results enable the exact computation of integrated yields and transverse momentum distributions of charm hadrons for different values of the spatial diffusion coefficient, providing the basis for a systematic determination of the charm transport coefficients. In addition, the limits of applicability of the approach will be discussed, determining the transverse-momentum region in which charm hadrons are described by a well-defined, positive distribution function.
